Description
Technical field:
The invention belongs to the gas storage technical field, relate to a kind of gas storage method that caisson that utilizes the Steel Lining structure stores high-pressure natural gas, high-pressure air, high-pressure carbon dioxide gas and high pressure hydrogen under normal temperature condition, to after gas pressurized, be stored in Steel Lining caisson inner chamber, for strategic reserves, accident deposit and peak regulation deposit, the particularly underground high pressure gas storage Preparation Method of a kind of dark embedding.
Background technique:
Rock gas is increasing as a kind of clean energy resource consumption, and market is in the state that supply falls short of demand, and urbanization process and energy-saving and emission-reduction also promote the rapid growth of natural gas consumption.In past 10 years, natural gas consumption has increased twice, and Future Ten year will keep same growth rate.Rock gas just progressively replaces other high pollution energy, becomes the clean energy resource of industry, urban life and traffic.The center of gravity of natural gas consumption progressively shifts to developed area from the oil gas field production area.Coastal area of southeastern China, the Yangtze River Delta and ring Bohai Sea three regions consumption figure will account for national aggregate consumption more than 50% the coming years, become Largest In China natural gas consumption center.And rock gas grown place and area of consumption be in same zone, distance and be subject to the restrictions such as import volume, production capacity and pipeline transmission capacity, supply falls short of demand on the whole for domestic rock gas, in short supply, and the gas famine appears in big city in rapid succession.Gas storage can realize that peak regulation, emergent air feed reach and stablize gas price, can realize the natural gas supply safety and steady, and therefore, gas storage is very necessary.
At present, worldwide gas storage mode only has pressurized storage, and gas storage on the ground adopts steel high-pressure cylindrical, spheric holder and gas holder, and cylindrical container is subject to bearing capacity restriction reserves little, spheric holder and gas holder are very high to material and manufacture process requirement, manufacture mounting cost higher and complicated.Long-distance transport pipes end and buried high pressure tube bank gas storage reserves are little; The tank area of gas storage on the ground requires to have certain fire safety spacing with station External building thing, and enclosure wall is outer can not build other buildings, if increase storage capacity, can only realize that enough places need to be arranged by increasing the storage tank number.Underground gas storage utilizes exhausted oil gas field, moisture porous stratum gas storage and salt ore bed to build gas storage gas storage, is having suitable architectonic place to adopt.Utilize exhausted oil field and gas field to build underground natural gas storage tank, need to grasp the gas storage stratum porosity, permeability, have or not water logging phenomenon, structure form and size, oil gas depth of stratum, about the accurate data of well bore and well construction and stratum and the isolated reliability of adjacent formations etc.; Utilize moisture porous stratum to build gas storage, require it to be formed by water-bearing sand and impervious bed, and general water-bearing sand is at 400～700 meters ability economically feasibles; Utilize salt cave and salt ore bed to build gas storage, salt deposit need to be dissolved to the hole of taking rear formation away and carry out natural gas-storing, but existing gas storage form all needs a large amount of rebasing gas (continuing the gas of the cushion between reservation or conduct work G&W in bank), and have a small amount of rebasing gas diffusion, annual must supplement a part of rebasing gas, be about work gas (gas that stores up in storage cycle into and again discharge) amount 6%, operating cost is high, floor space is large.
